13 Claims. (Cieza-i4) My invention relates to machines for packing iish in cans; and the broad object of the invention is the provision of mechanism for lifting a plurality of dressed sh from a conveyor and placing them in a can, so that the can may next be carried to the precooker and seamer and then processed.

More speciiic objects include the provision of improved means for picking up the fish from the feed conveyor, improved means for condensing the pack of picked up ish over the canning station, improved means for shaping theassembly of fish into a pack having the form of the can, improved means for inserting the shpack int-o the can, and improved means for changing the machine so as to pack a varying number of ilsh .in a can. n

Other objects of the invention together with the vforegoing will be made clear in the following description of my invention and the preferred .embodiment of means for practicing the same, which is illustrated in the drawings accompanying and forming part of this specification. I do not Ylimit myself to the showing made by the description and drawings, as I may adopt variations of the preferred form within the scope of .the appended claims.

Referring to the drawings from which portions and parts of the machine are omitted in order t simplify the views: Figure l is a side elevation of my packing machine. Figure 2 is an end elevation, the direction of the view being from the right of Figure 1. Figure 3 is a vertical sectional view, the plane of sec-` tion being indicated by the line 3-3 of Figure l.

Figure 4 is a plan view of the machine. Figures 5, 6, 7, 8 and 9 are detail views of units of mechanism. Figures 10 and 11 are diagrammatic views illustrating the packing of ve iish to a can.

In terms of broad inclusion, my ish packing4 and to the packing station in a step-by-step movement timed with the movement of the fish conveyors; and automatically operated means is provided for picking up from one of the lside, conveyors a number of sh constituting part of the pack-to `be put in one can,` and simultaneously from the other'side conveyor, a numberk of l'ish constituting the remaining part of the pack, and for bringing these two groups of fish, constituting the wholey pack or load for a can, toward each other 4until the bodies are intermeshed at the packing'station, with the tail ends sloping down sharply; and vthen moving the sh laterally into close proximity and lowering 'them until the tailends restonV the can bottom. Then as ythe supporting devices are withdrawn from theiishtto return to first position, automatically operating Ymeans subject the combinedgroups of sh to a pack-shaping pressure to mold them to the exact shape ,of the underlying can, and push the shaped iirstpack down and completely into the can.

Any practical number of such units may be `combined in one machine,` andI have chosen for this description and illustration a machine in which two cans are packed simultaneously .with eight iish each, four iish being taken from each si de yfor each can. The same ,machine is readily changed to pack four, live, six and seven fish in a can.

In greater detail and withv reference rst to Figure l, my packingmachine comprises a frame 2 for the most part conveniently Vmade of angle iron bolted or welded together, and in the lower part of which an electric motor 3 is arranged for driving the mechanism. The v motor,k is of the Vgeared type and is .connected by chain 4 runnine7 over` suitable sprockets withthe shaft. The motor speed and the severalratios aresuch as to turn the-shait B about 25to 30. R.. P.,M. llEorJer to drive the various mechanism is takenv from this shaft. v v

Driven from the shalt '6 through a 1:6 Geneva gear 'l is the shaft, connected ,by a series of speed change gears, collectively indicated bythe reference numeral 9, Figure 2, withthe shaft l2, which carries the sprockets over which runv the conveyor chains Ill, mounting the fish-carrying pocket blocks IB. As best shown in Figures 2 and 4, a conveyor of this sortcollectively designated with the reference numeral yI'L'is arrangedon each side of the machine, bringing the headless, eviscerated and cleaned fish invfrc'm `the left as viewed. in Figures l and 1l. IFish may be prepared by hand and placed in the pocket blocks oi the conveyors with the tailends pointing in, but it is contemplated that my packing machine will be placed in series with ldressing apparatus for preparing the lish; and in thiscase the conveyors eX- tend through the `entire series of machines from the loading station where the whole iishv are placed in the pocked blocks, through the head and tail cutting station,A evisceratlngy and .cleaning stations and into the packing machine constituting the present invention.

For these reasons it is desirable to drive all of the machines from one motor; and therefore a shaft I8, driven by gears |9 from shaft |2, and a shaft 2| driven by gears 22 from shaft 6 are extendedbackwardly (to the left of Figure 1) and connected to drive mechanism of the dressing apparatus. The shaft of the motor 3 is also ex tended back in the shaft -23 and connected to drive fast moving parts.

Five changes of speed are provided by the gears 9; and selection is made by means of the handles 24 to vary the number of fish from four to eight which are presented at the packing station by each of the side conveyors |1 with each forward step.

Journaled on the frame is a short shaft 28 on which is mounted the driving stud for the 1:6 Geneva gear 29. The shaft 28 is driven from shaft 8 by chain 30 running over suitable sprockets. Geneva gear 29 is xed on shaft 3|, which drives shaft 32 through the gears 33. Shaft 32 carries pulleys 34 over which passes the conveyor belt 36 which carries empty cans up the mid portion of the machine to the packing station, and then carries the packed cans forward and out of the machine to a disk or other suitable conveying means, not here shown which advances them another step in the procedure ending with the final cooking.

The shaft 28 also drives shaft 4| by a chain 42, running over suitable sprockets; and this shaft 4| operates all of the various mechanisms which cooperate to pick up the fish from the pocket blocks on the sh conveyors and place them in an orderly pack within the can.

Since a plurality of fish are packed in each can, the units of like mechanism are of course multiplied, and before describing the mechanism it will be helpfulto follow the handling of the fish constituting the pack for one can from the conveyor pocket blocks which have carried them to the packing station and there paused in their stepby-step movement. As the pocket blocks come to rest, a straight metal finger moves axially into the open end of each fish; and at the end of this movement, a clamping finger drops upon each fish to seize it. Each pair of clamping fingers holding the flsh as between thumb and forenger, then rises and moves toward the center ofthe machine. A similar action has taken place on the opposite side of the machine. In the present case, four sh are lifted from each side; and as these two groups of fish approach each other their tail ends interm'esh, the fish bodies sloping sharply down. At this point the holding fingers move laterally to bring all eight of the fish close together over the can lying directly below, The holding fingersV now drop to lower the fish partly into the can. Pack shaping arms forming a ring then compact the fish, the fingers release their holds and are withdrawn leaving the fish partially in the can and partially within the packshaping ring, from which they are pushed down into the can an instant before the next forward step of the can conveyor carries the lled can for- 'ward and an empty one into position for the next packing cycle.

The mechanism for handling the fish as just described is arranged on an elevator frame collectively designated by the reference number 46. It is seen in plan in Figure 4; and means are provided for raising and lowering the elevatorv frame so that the fish-holding fingers are raised and lowered as required in time with the operation of the conveyors and other mechanisms. The

elevator frame is. substantially rectangular in shape, and comprises two opposite and parallel sides 41 extending across the machine, and connected at their ends with the opposite and parallel ends 48, lying at right angles to the sides. All of these four frame members are essentially hollow or of channel section and each provides a slideway in which operating parts reciprocate.

Formed on the side of each framesi'de member 41 are two spaced upwardly extending lugs 49, to each of which is fixed a short rack 5|, slidable in the guide bracket 52 and in mesh with a pinion 53 lying within the bracket and fixed on the shaft 54, journaled in the two brackets on one side. The opposite side of the elevator frame is similarly provided with racks engaging pinions fixed on a shaft. An arm 56 fixed on each shaft is connected by links 51 with the arms of the rocker 58, journaled on the main frame 2 above the central long axis of the elevator frame; and a link 6| connects the rocker to the end of lever 62 pivoted on the fixed shaft 63 suitably held in brackets on the main frame 2. Pivoted to the lever is the shank 66 of the cam rider 61 reciprocated in a planned movement by the cam 68 fixed on the shaft 4|. It will be clear from the above that with rotation of the shaft 4| and cam 68, a timed movement is transmitted to the rocker 58, and thence to the shafts 54, and that like oscillation of the shafts and pinions 53 raises and lowers the elevator frame while maintaining its parallelism.

Means are provided on the elevator frame for picking up from the pocket blocks on each side of the machine the two groups of fish which together with the two groups from the opposite side constitute the packs for two cans, moving the fish lengthwise toward the center of the machine, and then sideways to divide them into two closely laid packs; and finally depositing each pack in the underlying can. Slidable in the channel of each frame member 48 at the right end thereof, as best shown in Figure 4, are four slide bars 1| to the top edge of each of which and at right angles thereto is fixed a track bar 12 extending to the center of the machine, and overlying the center of a pocket block on the flsh conveyor below during its pause. A retainer plate 13 overlying the track bar keeps the slide bars in their channel while permitting sliding thereof, each with its attached track bar.

The outer end of each track bar is provided with a head 14 adapting it to be connected by a pivot pin 16 to a bent link 11 which is pivoted at its other end to a lever arm 18, (left side of Figures 1 and 4). This lever arm is fixed to the end of a shaft 19 extending across the machine and carrying on its other end a similar lever arm connected by similar links to the track bars on that side. The shaft 19 is journaled in bearings 8| at each end. A similar shaft 82 and lever arms 83 are arranged on the opposite side of the elevator frame (right side of Figures 1 and 4); and are pivotally connected by links 84 with heads 86 on track bars 81 fixed on slide bars 88. Thus there are four sets of four track bars each, the two sets of track bars 12 (four on each side of the machine) connected to shaft 19; and the two sets of track bars 81 connected to shaft 82 On each shaft 19 and 82 is fixed an arm 9|,

pivotally connected by link 92 with the rocker 93 j ournaled on the bridge bar 94, supported at its two 'ends on the opposite sides "41 lof the elevator frame. 'The rocker-actuatedby the link 95 pivoted fat one end to the rocker, fand Sat the Aother to a lever arm 19B pivotally mounted on the aired shaft 63. The point of pivotal rconnection between flink 95 and 'lever 'arm '98 is made adjustable by providing va series of holes Y91 ina 'selooted one of which 'the pivot ilies. is done t'G V'ay the elfetlv'e throw of 'the lever ai'm, A'and .hence of the rocker L93, so that 'the movement of the track bars 12 and 81 may be varied when fthe machine is organized for packing less than full capacity. 'The lever arm v9b is oscillated by the shank B8 of the cam rider 99 actuated in a planned motion `by the cam |I fixed on the shaft 4|. It will :be clear from the above that with y'one -full rotation of the cam IUI, the track bars 12 are all moved 'into a close group of four on each side of the machine, and then returned to 'rst or open position in alignment with the underlying .pocket blocks, it being noted that both pocket blocks and track bars on one side of the machine are staggered with respect to those on the opposite side. Simultaneously, the track bars 81 are similarly moved into a 'close group of four 'on each side of the machine, and then returned to open position. I

A 'carrier including pick-up mechanism is slidably mounted on each track bar and all eight of the carriers and pick--up mechanisms on yeach side are 'actuated and controlled by the same means, 'such means on the two sides being operated Asimultaneously.

Slidable on :each track bar .is Aa carrier '403, 4conveniently formed of two spaced plates connected at their top edges and Within which the track bar lies. The plates aextend downwardly in spaced pendent legs forming a bracket |04 in which a heh-engaging linger I 05 is pivoted. The linger is preferably Vof the shape shown in Figure 3, and in the position shown, in which -it has just entered a sh, has upper and lower portions which are parallel, and connected by a vertical portion in which there is a `stilT knuckle joint |06. The pivot of the joint slants somewhat with respect to the sides of the vertical portion 'so that when the lower portion of the llinger i's `swung upwardly it passes to the side of overlying parts without interference. The lower part of selected fingers are turned up about the knuckle joint to prevent the fingers so turned up from picking up a sh, when the machine is vorganized for packing less than its full capacity of eight in one can. The ringer has a lug |01 xed thereon to seat against the bracket so as to limit the upward pivotal swing of the finger assembly while permitting it to swing downwardly. The nger is moved `downwardly by the vertical push rod |08 on the upper part of which is a roller |09 bearing .against the under face of the associated track bar constituting a cam I. As shown in Figure 3, this cam is shaped to throw the push rod and finger downwardly as the carrier assembly approaches the center of the machine. In order to keep the push rod in upright position and in substantial parallelism at all times, the rod is also pivotally connected to a lever |I2 pivoted on the bracket in approximate parallelism to the iinger |05. A spring ||3 interposed between the lever and the carrier tends to keep the linger vand connected parts in the uppermost position, with the roller |09 against the cam I4 I; 4and thus it eiTects the recovery movement of the finger after the sh has been released.

Means are also included in the carrier assembly to clamp down on the rish in which the fingerhas entered so as to :hold it thereon. .if the bar wt be considered .a ringer, the bar IM pivoter. on the lu'g |01 'may be considered fa thu-rnb, 'since the ac'- tion of the two is substantially 'the saine with regard 'to the rish as that of ringer and `tl'i'tunb would be if, the lish were moved by the hand. 4`A spring fmt interposed between the thumb bar and lever :112 maintains .a con'timidi pressure tending to depress the end ofthe bar, but the 'position or the 'bar ris controlled :by 'the' round nose plate 'II'I which extends across the rear portions 'of all the `thumb bars and is pivotally mounted by means of a short shaft 11% projecting 'from each end or the plate and iournaled'in 'a bracket -bearing |Ii9 inked fon the underside ofthe bar 12|. Pressure of the plate nose upon the adjacent Vends 'o'i the "thumb b'ars iat the .proper tilne raises 'the Irish-engaging ends 'to release 'the heh, while lrelaxation of such pressure permits the springs Ht to act to 'engage the thumb bars with the sh. Thi'srockin'g the plate |11 '-s accomplished by hiring to each end of the plate an arm i212 on the free end o'f which is ournale'd a roller ist. The roller overlies a loar |"2'4 pivotally supported on linksj''ZB, pivt'e'd 'tothe ends 'of the elevator frame mer'nber 541. The 'bar i324 is swung to the leit (of Figure 3l, and ofcourse upwardly, he- -cause the 'Supporting Alinks are short, by the lever arm |21, connected by link 5|28 'to the bar and hired on the shaft its, journa'led in 'the bridge 94. The rsfr-rait is Arocked by means of a link @3| (Figure 2) pivotally connecting-an ann *iai on the shaft to an arm |313 on the shaft |34, journaied in bearings `fixed on the main frame members. lAt its 'opposite end the shai-t |34 is provided with an arm its carrying a earn roller which engages 'the cam face of the earn |31. vcani operates to turn the shaft |30, 'the bar |"2'4 on each side is pulled over and upwardly, carrying 'up the roller sh'o'd arms I`22 'and depressing the nose of the .plate |"I1, thus raising the sh 'engaging en'ds'of the thumb b'a'rs.

Means are provided vfor moving the carriersy toward the center of the machine. On the underside of each carrier in the 'group on each side of the vmachine is a 'squarenotch tting over a.

bar IZI. Thisbar extends 'across the elevator frame and 'at 'each of its ends is fixed to a rack IIII which lies vin 'the channel or slideway of 'the elevator frame member '47, and is in mesh with a pinion |42 also in the channel. Since there is a bar 12| 'on each side o'f the frame, there are two racks |41 in `each channel; and these mesh with l 'the pinion Von opposite sides as best shown 'in Figures 8 andi?,y 'Each pinion yis fixed on a short shaft |43, vollrn'a'led, in the bottom wall yof the frame member and in 'the cover plate |44, both bottom wall and cover plate being heavily bossed at this point. On the upper end of each shaft is a `second pinion U45 and these upper pinions are "connected Jfor simultaneous and like movement by a rack bar I4t slidably arranged in slideways 'formed in the cover platebosses.

Extending upwardly on the rack bar is a lug |41 connected bylink |48 with the lever arm '|49 p'ivo'ted von the fixed shaft 6'3. The lever arm is oscillated bythe shank IBI of vthe cam rider'lr52, actuated in a planned motion by cam |53. VRotation oi this cam therefore moves the twobars I2! in a timed movement from the sides of 'the machine toward the center andbaok again while maintaining them at all times in parallelism; each bar in such .movement carrying with it the associated group of carriers.

When the Means are provided for compacting-into the oval shape of the can, the two groups vof interlapping sh, and then pressing the shaped pack down into the can. Means are also provided for positioning a succession of cans under the packshaping device and for holding them while the pack is pressed into them.

Since the machine'here described acts upon two groups of fish fromeach side conveyor to form two shaped packs, two cans at a time are presented at the packing station under the packshaping means by the conveyor belt-36 timed by its driving means to move in the intervals between the shaping of the packs,

'I'he can conveyor belt enters the machinefrom the left as viewed in Figure l; and carries a succession of flat oval cans |55 which Ahave. been placed thereon in approximately accurate position with the long axes lying crosswise of the belt. Support is provided for the upper reach of the belt at the packing station by a platen |56, Figure l, carried on a frame |51, having inverted Y-shape arms |58 which provide bearings for the cam shaft |59 which operates the can positioning and pack-shaping devices. These arms also r provide a mountingfor fixed shafts |6| and |62 on which the operating levers for such. devices are pivoted. The platen frame |51 is supported on two fixed shafts |63 extending across the main frame of the machine.

As the can conveyor `pauses with the two cans below the pack-shaping means, push plates |64,

Figure '1 each havingtwo shallow notches.l |65 in the edge to engage the ends of two closely spaced cans, move in from each side and Vpush the cansE accurately into position and then hold them there. One of the plates is carried `on the end of an arm |66, Figure 3, pivoted on the fixed shaft |62 and extended below theshaft in the short lever arm |61. The other plate is carried on the arm |68 pivoted on the shaft I6 and connected to the lever arm |61 for simultaneous and like movement with its twin by a link |69.

Timed movement to withdrawthe can positioning and holding means is imparted' by a roller |10, journaled on the arm |66 and rengaging the face of a cam |1| fixed on the shaft |59 which is rotated by a chain |12 from shaft 2|. 'I'hecan positioning and holding plates are -pulled toward each other to engage the cansbyv the tension spring |13 as permitted` by the cam.

Immediately above the positioned cans on each side are the pack-shaping arms |14 varranged on a base frame |15'slidablymounted on the two fixed shafts |63. The frame is provided with vertical studs |16 on which the arms are adiustably and replaceably mounted. ".[henarrns4 |14comprise a thin wall. a little lessin vertical height than the can, and shaped as shownfinv Figure 7, so that when the two arms -on opposite sides .of the cans are brought together they enclose two oval spaces corresponding in shapev and size` to the openings into the twounderlying cans. Because the fish-engaging fingers, |56 fall close to the top edge of the cans just before theyfare withdrawn, notches |11 areformed in thearm wall to permit the fingers to be withdrawn without interference. The arms are replaceable with arms having a different numberl and spacing of notches when the machine is set up for a different numberoffishtoacan.

The arms are moved toward each otherto shape the pack by links |19, one of whichfis connected to a lever arm |80 pivoted on the shaft |62 and connected by link |8|e withthe lower end of lever |82, pivoted onthe'shaft |6| and connected at its'upper end with the `other link |19. .The lever arm |80 has journaled thereon a cam roller |83 riding on the cam |84 fixed on the shaft |59 by the side of cam |12. Rotation of the cam pulls the pack-shaping arms together, against the pull of a tension vspring |86, connecting the two lever arms |80 and |82. This spring effects the recovery movement of the armsyas soon as the cam permits which is immediately after the fish packs have been pushed into the cans.

After the fish pack has been rshaped and the holding fingers withdrawn, the head ends of the fish may not sink fully into the cans. Means are therefore provided to insure the pack fully entering the can. Disposed vertically on one side of the bridge bar 94 and fixed thereon by means of a bracket |92 is a slide bearing |93 in which a rod |94 is reciprocated in a timed movement by a cam |96 conveniently formed on the hub of the cam |53 fixed on shaft 4|. The planned motion of the cam is transmitted to the rod |94 by means of a lever |91 pivoted on the shaft 53 and connected to the rod by link |98. Thelower end of the rod is provided with a pair of spaced press plates |99. the same shape but a little smaller than the can openings so that when the plates are moved downwardly they press the fish packs out of the packing shaping arms and into the cans. Recovery movement as controlled by the cam is effected by a compression spring 20| interposed betweenthe end of the slide bearing and the rod |94. Y

As above explained my machine is organized to pack eight fish in each can, but on account of variation in size it is sometimes necessary to reduce this number. By making four simple adjustments my machine may be set up to pack seven, six, five or four fish to a can instead 0f its full capacity. Thus if five fish are to be packed in a can the conveyor speed is changed by shifting the gears 9 so as to advance the side conveyors to place at the pick-up station with each forward step fivev fish on each side. Secondl the first two fish-holding fingers A and B (referring to Figure 10), and the last finger H on the right side of the machine (as viewed by one stand- -ing at the left of the machine asin Figure 1);

and the first finger S, and the last twc fingers Y and Z on the left side are folded back so as to render the'pick-up mechanism at these points in operative. This is shown in diagram in Figure l0; and the fish to lie-picked up, and the two packs formed are shown in Figure l1. With the remaining operative fingers, five fish vare picked up from each side, the two fish from fingers C and D on the right intermeshing with three fish from fingers T, U and V on the left to form the first pack I, Figurell; and the three fish from the next fingers' E, F and C- on the right intermeshing with' two from the next fingers W and X on the left to form the second pack II. The third adjustment to be made is the throw of lever arm 95, by selection of the pivotal point of connection with link 95 in one of the five holes S1. This varies the distance which the track bars 12 and 87 moveto bring the intermeshed fish together. For example, in a pack of eight fish, the spacing of the pick-up fingers is about 1" between centers, but for a pack of five, the spacing is about legs". Fourth, the packshaping arms |14 are replaced with arms having an appropriate spacing of the notches |11 since the spacing of the fingers is'different for five fish in a pack than for eight.

-If-seven.4 fishare vto be'packed in each' can; the first vpick-upffinger:A on the fright andthe last one-Z on the' left'vare turned back, .sol that ineach'groupthree'hsh comein from one side and kioinlifrom the opposite side to make Seven in each group. Y' Suitable shifting of the gears, and changes' in pack-shaping larms and in the throw .of the-lever arm 96 are also made.

The press plates 99 actuated by cam |96, now descend to press the shaped packs into the cans; and as they recover, the packshaping arms and can holding plates are withdrawn, and the can conveyor moves forward one step to carry the lled cans toward the discharge end of the conveyor, and replace them with empty ones. In the meantime all parts have returned to first position for a repetition of the cycle.
